The Sprint Cup Series rookie got behind the wheel of grandfather Richard Childress' Camping World Truck Series machine to win the Pocono Mountains 150. It's also the first victory for Chevrolet in the Truck Series this year and the first time Toyota didn't take the checkered flag.

Dillon's biggest challenger was Cup rival Kyle Larson, who started on the pole and led twice for 21 total laps before engine issues relegated him to an 18th-place finish. Cup regular Clint Bowyer filled in for an injured John Wes Townley and finished fourth.

"I felt like Kyle and I had the best two trucks," Dillon said. "And I knew Clint, with his experience, was going to be there. He came off pit road right in front of us on that (last) stop and I was loose at that point in time. I ran him back down and was on his bumper when the caution came out so I was pretty confident that we had a truck that could win at that point.

"Kyle was very good at the beginning. I felt like we could stay with him. Clean air was pretty important. I don't know how long we could've stayed in front of him if we had that clean air "» but also, you're saving fuel at certain points during that run, so all out there at the end would've been a good race."

With two laps to go in NASCAR's version of overtime, Dillon was given some extra help on the final restart of the race by second-place finisher Johnny Sauter. Sauter pushed Dillon, the 2011 Truck Series champion, on the outside past Bowyer, who didn't get a good restart.

Even though he didn't get the win, Sauter was satisified with second Saturday.

"I gave the (No.) 3 the best push I could and probably pushed him too far away to even have a run at him," Sauter said. "He had a really good truck there at the end. Just proud of everybody. This is my best finish here in a place that I'm not particularly fond of."

The caution that sent the race into overtime turned controversial quickly.

On a restart on lap 53, Tyler Reddick and German Quiroga were battling for seventh in the Tunnel Turn when both drivers got loose. Both drivers saved their trucks from spinning, but Quiroga came back into Reddick's right rear to turn him into the outside wall.

On the ensuing restart with three laps to go, Reddick got his revenge.

In the same spot where he was turned a few laps before, Reddick drove straight to the back bumper of Quiroga's No. 77. Quiroga got sideways and made contact with Tyler Young, who then smacked the outside wall with his right side.

Reddick made sure Quiroga went around, though, and turned hard left into Quiroga, sending him hard into the short-chute wall.

NASCAR parked Reddick for the remainder of the race and mandated a visit to the series' hauler post-race.
